The key difference
GOV.UK describes Cat S as repairable after structural damage and Cat N as repairable after non-structural damage. Both can be used again if repaired to a roadworthy condition.
Why the distinction matters
Structural damage makes repair evidence and independent assessment especially important. Non-structural does not automatically mean unimportant, simple or cheap damage.
What both records have in common
Both can affect price, insurance and future resale. In either case, ask what happened, what was repaired and what evidence exists.
How to compare examples
Do not compare categories in the abstract. Compare the individual car’s price, history, repair documentation, condition and insurance quote with realistic alternatives.
When to get help
If you cannot confidently assess the repair evidence or vehicle condition, consider an independent inspection before you buy.
